BACKGROUND

The goal of hybrid development is to combine, in a single hybrid,various desirable traits. For field crops, these traits may includeresistance to diseases and insects, resistance to heat and drought,reducing the time to crop maturity, greater yield, and better agronomicquality. With mechanical harvesting of many crops, uniformity of plantcharacteristics such as germination, stand establishment, growth rate,maturity, and plant and ear height is important. Traditional plantbreeding is an important tool in developing new and improved commercialcrops.

SUMMARY

Provided is a novel maize, Zea mays L., variety, seed, plant, and itsparts designated as X05H214, produced by crossing two maize inbredvarieties. The hybrid maize variety X05H214, the seed, the plant and itsparts produced from the seed, and variants, mutants and minormodifications of maize X05H214 are provided. Processes are provided formaking a maize plant containing in its genetic material one or moretraits introgressed into X05H214 through locus conversion and/ortransformation, and to the maize seed, plant and plant parts producedthereby. Methods for producing maize varieties derived from hybrid maizevariety X05H214 are also provided. Also provided are maize plants havingall the physiological and morphological characteristics of the hybridmaize variety X05H214.

The hybrid maize plant may further comprise a cytoplasmic or nuclearfactor capable of conferring male sterility or otherwise preventingself-pollination, such as by self-incompatibility. Parts of the maizeplants disclosed herein are also provided, for example, pollen obtainedfrom an hybrid plant and an ovule of the hybrid plant.

Seed of the hybrid maize variety X05H214 is provided and may be providedas a population of maize seed of the variety designated X05H214.

Compositions are provided comprising a seed of maize variety X05H214comprised in plant seed growth media. In certain embodiments, the plantseed growth media is a soil or synthetic cultivation medium. In specificembodiments, the growth medium may be comprised in a container or may,for example, be soil in a field.

Hybrid maize variety X05H214 is provided comprising an added heritabletrait. The heritable trait may be a genetic locus that is a dominant orrecessive allele. In certain embodiments of the invention, the geneticlocus confers traits such as, for example, male sterility, waxy starch,herbicide tolerance or resistance, insect resistance, resistance tobacterial, fungal, nematode or viral disease, and altered or modifiedfatty acid, phytate, protein or carbohydrate metabolism. The geneticlocus may be a naturally occurring maize gene introduced into the genomeof a parent of the variety by backcrossing, a natural or inducedmutation, or a transgene introduced through genetic transformationtechniques. When introduced through transformation, a genetic locus maycomprise one or more transgenes integrated at a single chromosomallocation.

A hybrid maize plant of the variety designated X05H214 is provided,wherein a cytoplasmically-inherited trait has been introduced into thehybrid plant. Such cytoplasmically-inherited traits are passed toprogeny through the female parent in a particular cross. An exemplarycytoplasmically-inherited trait is the male sterility trait.Cytoplasmic-male sterility (CMS) is a pollen abortion phenomenondetermined by the interaction between the genes in the cytoplasm and thenucleus. Alteration in the mitochondrial genome and the lack of restorergenes in the nucleus will lead to pollen abortion. With either a normalcytoplasm or the presence of restorer gene(s) in the nucleus, the plantwill produce pollen normally. A CMS plant can be pollinated by amaintainer version of the same variety, which has a normal cytoplasm butlacks the restorer gene(s) in the nucleus, and continues to be malesterile in the next generation. The male fertility of a CMS plant can berestored by a restorer version of the same variety, which must have therestorer gene(s) in the nucleus. With the restorer gene(s) in thenucleus, the offspring of the male-sterile plant can produce normalpollen grains and propagate. A cytoplasmically inherited trait may be anaturally occurring maize trait or a trait introduced through genetictransformation techniques.

A tissue culture of regenerable cells of a plant of variety X05H214 isprovided. The tissue culture can be capable of regenerating plantscapable of expressing all of the physiological and morphological orphenotypic characteristics of the variety and of regenerating plantshaving substantially the same genotype as other plants of the variety.Examples of some of the physiological and morphological characteristicsof the variety X05H214 include characteristics related to yield,maturity, and kernel quality, each of which is specifically disclosedherein. The regenerable cells in such tissue cultures may, for example,be derived from embryos, meristematic cells, immature tassels,microspores, pollen, leaves, anthers, roots, root tips, silk, flowers,kernels, ears, cobs, husks, or stalks, or from callus or protoplastsderived from those tissues. Maize plants regenerated from the tissuecultures of the invention, the plants having all the physiological andmorphological characteristics of variety X05H214 are also provided.

A method of producing hybrid maize seed comprising crossing a plant ofvariety PH1M1K with a plant of variety PH1TRA is provided. In a cross,either parent may serve as the male or female. Processes are alsoprovided for producing maize seeds or plants, which processes generallycomprise crossing a first parent maize plant with a second parent maizeplant, wherein at least one of the first or second parent maize plantsis a plant of the variety designated X05H214. In such crossing, eitherparent may serve as the male or female parent. These processes may befurther exemplified as processes for preparing hybrid maize seed orplants, wherein a first hybrid maize plant is crossed with a secondmaize plant of a different, distinct variety to provide a hybrid thathas, as one of its parents, the hybrid maize plant variety X05H214. Inthese processes, crossing will result in the production of seed. Theseed production occurs regardless of whether the seed is collected ornot.

In some embodiments, the first step in “crossing” comprises planting,often in pollinating proximity, seeds of a first and second parent maizeplant, and in many cases, seeds of a first maize plant and a second,distinct maize plant. Where the plants are not in pollinating proximity,pollination can nevertheless be accomplished by transferring a pollen ortassel bag from one plant to the other.

A second step comprises cultivating or growing the seeds of said firstand second parent maize plants into plants that bear flowers (maizebears both male flowers (tassels) and female flowers (silks) in separateanatomical structures on the same plant). A third step comprisespreventing self-pollination of the plants, i.e., preventing the silks ofa plant from being fertilized by any plant of the same variety,including the same plant. This can be done, for example, by emasculatingthe male flowers of the first or second parent maize plant, (i.e.,treating or manipulating the flowers so as to prevent pollen production,in order to produce an emasculated parent maize plant).Self-incompatibility systems may also be used in some hybrid crops forthe same purpose. Self-incompatible plants still shed viable pollen andcan pollinate plants of other varieties but are incapable of pollinatingthemselves or other plants of the same variety.

A fourth step may comprise allowing cross-pollination to occur betweenthe first and second parent maize plants. When the plants are not inpollinating proximity, this can be done by placing a bag, usually paperor glassine, over the tassels of the first plant and another bag overthe silks of the incipient ear on the second plant. The bags are left inplace for at least 24 hours. Since pollen is viable for less than 24hours, this assures that the silks are not pollinated from other pollensources, that any stray pollen on the tassels of the first plant isdead, and that the only pollen transferred comes from the first plant.The pollen bag over the tassel of the first plant is then shakenvigorously to enhance release of pollen from the tassels, and the shootbag is removed from the silks of the incipient ear on the second plant.Finally, the pollen bag is removed from the tassel of the first plantand is placed over the silks of the incipient ear of the second plant,shaken again and left in place. Yet another step comprises harvestingthe seeds from at least one of the parent maize plants. The harvestedseed can be grown to produce a maize plant or hybrid maize plant.

Maize seed and plants are provided that are produced by a process thatcomprises crossing a first parent maize plant with a second parent maizeplant, wherein at least one of the first or second parent maize plantsis a plant of the variety designated X05H214. Maize seed and plantsproduced by the process are first generation hybrid maize seed andplants produced by crossing an inbred with another, distinct inbred.Seed of an F1 hybrid maize plant, an F1 hybrid maize plant and seedthereof, specifically the hybrid variety designated X05H214 is provided.

Plants described herein can be analyzed by their “genetic complement.”This term is used to refer to the aggregate of nucleotide sequences, theexpression of which defines the phenotype of, for example, a maizeplant, or a cell or tissue of that plant. A genetic complement thusrepresents the genetic make up of a cell, tissue or plant. Provided aremaize plant cells that have a genetic complement in accordance with themaize plant cells disclosed herein, and plants, seeds and diploid plantscontaining such cells.

Plant genetic complements may be assessed by genetic marker profiles,and by the expression of phenotypic traits that are characteristic ofthe expression of the genetic complement, e.g., isozyme typing profiles.It is understood that variety X05H214 could be identified by any of themany well-known techniques used for genetic profiling disclosed herein.

Forexample, a percent identity of 90% between X05H214 and other varietymeans that the two varieties have the same homozygous alleles at 90% oftheir loci.

Phenotypic Characteristics of X05H214

Pioneer Brand Hybrid Maize Variety X05H214 is a single cross, yellowendosperm maize variety and can be made by crossing inbreds PH1M1K andPH1TRA. Locus conversions of Hybrid Maize Variety X05H214 can be made bycrossing inbreds PH1M1K and PH1TRA wherein PH1M1K and/or PH1TRA comprisea locus conversion(s). The yield platform BLUP value for Hybrid MaizeVariety X05H214 is 216.4 bushels per acre. The yield platform BLUP is avalue derived by averaging for all members of the platform weighted bythe inverse of the Standard Errors.

The maize variety has shown uniformity and stability within the limitsof environmental influence for all the traits as described in theVariety Description Information (Table 1, found at the end of thesection). The inbred parents of this maize variety have beenself-pollinated and ear-rowed a sufficient number of generations withcareful attention paid to uniformity of plant type to ensure thehomozygosity and phenotypic stability necessary for use in commercialhybrid seed production. The variety has been increased both by hand andin isolated fields with continued observation for uniformity. No varianttraits have been observed or are expected in X05H214.

Hybrid Maize Variety X05H214 can be reproduced by planting seeds of theinbred parent varieties, growing the resulting maize plants under crosspollinating conditions, and harvesting the resulting seed usingtechniques familiar to the agricultural arts.

Genotypic Characteristics of X05H214

In addition to phenotypic observations, a plant can also be described byits genotype. The genotype of a plant can be characterized through agenetic marker profile. There are many laboratory-based techniquesavailable for the analysis, comparison and characterization of plantgenotype; among these are Isozyme Electrophoresis, Restriction FragmentLength Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs(RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNAAmplification Fingerprinting (DAF), Sequence Characterized AmplifiedRegions (SCARs), Amplified Fragment Length Polymorphisms (AFLPs), SimpleSequence Repeats (SSRs) which are also referred to as Microsatellites,and Single Nucleotide Polymorphisms (SNPs). For example, see Berry, Don,et aL, “Assessing Probability of Ancestry Using Simple Sequence RepeatProfiles: Applications to Maize Hybrids and Inbreds”, Genetics, 2002,161: 813-824, and Berry, Don et aL, “Assessing Probability of AncestryUsing Simple Sequence Repeat Profiles: Applications to Maize InbredLines and Soybean Varieties”, Genetics, 2003, 165: 331-342, which areincorporated by reference herein in their entirety.

Particular markers used for these purposes may include any type ofmarker and marker profile which provides a means of distinguishingvarieties. A genetic marker profile can be used, for example, toidentify plants of the same variety or related varieties or to determineor validate a pedigree. In addition to being used for identification ofmaize variety X05H214 and its plant parts, the genetic marker profile isalso useful in developing a locus conversion of X05H214.

Methods of isolating nucleic acids from maize plants and methods forperforming genetic marker profiles using SNP and SSR polymorphisms arewell known in the art. SNPs are genetic markers based on a polymorphismin a single nucleotide. A marker system based on SNPs can be highlyinformative in linkage analysis relative to other marker systems in thatmultiple alleles may be present.

A method comprising isolating nucleic acids, such as DNA, from a plant,a plant part, plant cell or a seed of the maize varieties disclosedherein is provided. The method can include mechanical, electrical and/orchemical disruption of the plant, plant part, plant cell or seed,contacting the disrupted plant, plant part, plant cell or seed with abuffer or solvent, to produce a solution or suspension comprisingnucleic acids, optionally contacting the nucleic acids with aprecipiting agent to precipitate the nucleic acids, optionallyextracting the nucleic acids, and optionally separating the nucleicacids such as by centrifugation or by binding to beads or a column, withsubsequent elution, or a combination thereof. If DNA is being isolated,an RNase can be included in one or more of the method steps. The nucleicacids isolated can comprise all or substantially all of the genomic DNAsequence, all or substantially all of the chromosomal DNA sequence orall or substantially all of the coding sequences (cDNA) of the plant,plant part, or plant cell from which they were isolated. The nucleicacids isolated can comprise all, substantially all, or essentially allof the genetic complement of the plant. The nucleic acids isolated cancomprise a genetic complement of the maize variety. The amount and typeof nucleic acids isolated may be sufficient to permit whole genomesequencing of the plant from which they were isolated or chromosomalmarker analysis of the plant from which they were isolated.

The methods can be used to produce nucleic acids from the plant, plantpart, seed or cell, which nucleic acids can be, for example, analyzed toproduce data. The data can be recorded. The nucleic acids from thedisrupted cell, the disrupted plant, plant part, plant cell or seed orthe nucleic acids following isolation or separation can be contactedwith primers and nucleotide bases, and/or a polymerase to facilitate PCRsequencing or marker analysis of the nucleic acids. In some examples,the nucleic acids produced can be sequenced or contacted with markers toproduce a genetic profile, a molecular profile, a marker profile, ahaplotype, or any combination thereof. In some examples, the geneticprofile or nucleotide sequence is recorded on a computer readablemedium. In other examples, the methods may further comprise using thenucleic acids produced from plants, plant parts, plant cells or seeds ina plant breeding program, for example in making crosses, selectionand/or advancement decisions in a breeding program. Crossing includesany type of plant breeding crossing method, including but not limited tocrosses to produce hybrids, outcrossing, selfing, backcrossing, locusconversion, introgression and the like.

Favorable genotypes and or marker profiles, optionally associated with atrait of interest, may be identified by one or more methodologies. Insome examples one or more markers are used, including but not limited toAFLPs, RFLPs, ASH, SSRs, SNPs, indels, padlock probes, molecularinversion probes, microarrays, sequencing, and the like. In somemethods, a target nucleic acid is amplified prior to hybridization witha probe. In other cases, the target nucleic acid is not amplified priorto hybridization, such as methods using molecular inversion probes (see,for example Hardenbol et al. (2003) Nat Biotech 21:673-678). In someexamples, the genotype related to a specific trait is monitored, whilein other examples, a genome-wide evaluation including but not limited toone or more of marker panels, library screens, association studies,microarrays, gene chips, expression studies, or sequencing such aswhole-genome resequencing and genotyping-by-sequencing (GBS) may beused. In some examples, no target-specific probe is needed, for exampleby using sequencing technologies, including but not limited tonext-generation sequencing methods (see, for example, Metzker (2010) NatRev Genet 11:31-46; and, Egan et al. (2012) Am J Bot 99:175-185) such assequencing by synthesis (e.g., Roche 454 pyrosequencing, Illumina GenomeAnalyzer, and Ion Torrent PGM or Proton systems), sequencing by ligation(e.g., SOLiD from Applied Biosystems, and Polnator system from AzcoBiotech), and single molecule sequencing (SMS or third-generationsequencing) which eliminate template amplification (e.g., Helicossystem, and PacBio RS system from Pacific BioSciences). Furthertechnologies include optical sequencing systems (e.g., Starlight fromLife Technologies), and nanopore sequencing (e.g., GridION from OxfordNanopore Technologies). Each of these may be coupled with one or moreenrichment strategies for organellar or nuclear genomes in order toreduce the complexity of the genome under investigation via PCR,hybridization, restriction enzyme (see, e.g., Elshire et al. (2011) PLoSONE 6:e19379), and expression methods. In some examples, no referencegenome sequence is needed in order to complete the analysis. X05H214 andits plant parts can be identified through a molecular marker profile.Such plant parts may be either diploid or haploid. Also encompassed anddescribed are plants and plant parts substantially benefiting from theuse of variety X05H214 in their development, such as variety X05H214comprising a locus conversion.

Comparisons of Pioneer Maize Variety Hybrid X05H214

A breeder uses various methods to help determine which plants should beselected from segregating populations and ultimately which inbredvarieties will be used to develop hybrids for commercialization. Inaddition to knowledge of the germplasm and plant genetics, a part of thehybrid selection process is dependent on experimental design coupledwith the use of statistical analysis. Experimental design andstatistical analysis are used to help determine which hybridcombinations are significantly better or different for one or moretraits of interest. Experimental design methods are used to assess errorso that differences between two hybrid varieties can be more accuratelyevaluated. Statistical analysis includes the calculation of mean values,determination of the statistical significance of the sources ofvariation, and the calculation of the appropriate variance components.One of ordinary skill in the art of plant breeding would know how toevaluate the traits of two plant varieties to determine if there is nosignificant difference between the two traits expressed by thosevarieties. For example, see Fehr, Walt, Principles of CultivarDevelopment, pages 261-286 (1987). Mean trait values may be used todetermine whether trait differences are significant. Trait values shouldpreferably be measured on plants grown under the same environmentalconditions, and environmental conditions should be appropriate for thetraits or traits being evaluated. Sufficient selection pressure shouldbe present for optimum measurement of traits of interest such asherbicide tolerance or herbicide, insect or disease resistance. Forexample, a locus conversion of X05H214 for herbicide resistance ortolerance should be compared with an isogenic counterpart in the absenceof the herbicide. In addition, a locus conversion for insect or diseaseresistance should be compared to the isogenic counterpart, in theabsence of disease pressure or insect pressure.

In Table 2, found at the end of this section, BLUP, Best Linear UnbiasedPrediction, values are reported for maize hybrid X05H214 and/or maizehybrid X05H214 comprising locus conversions. The BLUP values andStandard Errors, SE, are reported for numerous traits. In Table 2, maizehybrid X05H214 listed in a different row with the same traits indicatesthat the transgenic event and/or transgene construct used in the locusconversion are different.

Development of Maize Hybrids using X05H214

During the inbreeding process in maize, the vigor of the varietiesdecreases. However, vigor is restored when two different inbredvarieties are crossed to produce the hybrid progeny (F1). An importantconsequence of the homozygosity and homogeneity of the inbred varietiesis that the hybrid between a defined pair of inbreds may be reproducedindefinitely as long as the homogeneity of the inbred parents ismaintained. Once the inbreds that create a superior hybrid have beenidentified, a continual supply of the hybrid seed can be produced usingthese inbred parents and the hybrid corn plants can then be generatedfrom this hybrid seed supply.

X05H214 may also be used to produce a double cross hybrid or a three-wayhybrid. A single cross hybrid is produced when two inbred varieties arecrossed to produce the F1 progeny. A double cross hybrid is producedfrom four inbred varieties crossed in pairs (A×B and C×D) and then thetwo F1 hybrids are crossed again (A×B)×(C×D). A three-way cross hybridis produced from three inbred varieties where two of the inbredvarieties are crossed (A×B) and then the resulting F1 hybrid is crossedwith the third inbred variety (A×B)×C. In each case, pericarp tissuefrom the female parent will be a part of and protect the hybrid seed.

Another form of commercial hybrid production involves the use of amixture of male sterile hybrid seed and male pollinator seed. Whenplanted, the resulting male sterile hybrid plants are pollinated by thepollinator plants. This method is primarily used to produce grain withenhanced quality grain traits, such as high oil, because desired qualitygrain traits expressed in the pollinator will also be expressed in thegrain produced on the male sterile hybrid plant. In this method thedesired quality grain trait does not have to be incorporated by lengthyprocedures such as recurrent backcross selection into an inbred parentline. One use of this method is described in U.S. Pat. Nos. 5,704,160and 5,706,603.

Molecular data from X05H214 may be used in a plant breeding process.Nucleic acids may be isolated from a seed of X05H214 or from a plant,plant part, or cell produced by growing a seed of X05H214, or from aseed of X05H214 with a locus conversion, or from a plant, plant part, orcell of X05H214 with a locus conversion. One or more polymorphisms maybe isolated from the nucleic acids. A plant having one or more of theidentified polymorphisms may be selected and used in a plant breedingmethod to produce another plant.

Introduction of a new trait or locus into Hybrid Maize Variety X05H214

Hybrid variety X05H214 represents a new base genetic line into which anew locus or trait may be introduced or introgressed. Transformation andbackcrossing represent two methods that can be used to accomplish suchan introgression. The term locus conversion is used to designate theproduct of such an introgression.

To select and develop a superior hybrid, it is necessary to identify andselect genetically unique individuals that occur in a segregatingpopulation. The segregating population is the result of a combination ofcrossover events plus the independent assortment of specificcombinations of alleles at many gene loci that results in specific andunique genotypes. Once such a variety is developed its value to societyis substantial since it is important to advance the germplasm base as awhole in order to maintain or improve traits such as yield, diseaseresistance, pest resistance and plant performance in extreme weatherconditions. Locus conversions are routinely used to add or modify one ora few traits of such a line and this further enhances its value andusefulness to society.

Backcrossing can be used to improve inbred varieties and a hybridvariety which is made using those inbreds. Backcrossing can be used totransfer a specific desirable trait from one variety, the donor parent,to an inbred called the recurrent parent which has overall goodagronomic characteristics yet that lacks the desirable trait. Thistransfer of the desirable trait into an inbred with overall goodagronomic characteristics can be accomplished by first crossing arecurrent parent to a donor parent (non-recurrent parent). The progenyof this cross is then mated back to the recurrent parent followed byselection in the resultant progeny for the desired trait to betransferred from the non-recurrent parent.

Traits may be used by those of ordinary skill in the art to characterizeprogeny. Traits are commonly evaluated at a significance level, such asa 1%, 5% or 10% significance level, when measured in plants grown in thesame environmental conditions. For example, a locus conversion ofX05H214 may be characterized as having essentially the same phenotypictraits as X05H214. The traits used for comparison may be those traitsshown in Table 1 or Table 2. Molecular markers can also be used duringthe breeding process for the selection of qualitative traits. Forexample, markers can be used to select plants that contain the allelesof interest during a backcrossing breeding program. The markers can alsobe used to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants.

A backcross or locus conversion of X05H214 can be developed when DNAsequences are introduced through backcrossing (Hallauer et al., 1988),with a parent of X05H214 utilized as the recurrent parent. Bothnaturally occurring and transgenic DNA sequences may be introducedthrough backcrossing techniques. A backcross or locus conversion mayproduce a plant with a trait or locus conversion in at least one or morebackcrosses, including at least 2 backcrosses, at least 3 backcrosses,at least 4 backcrosses, at least 5 backcrosses and the like. Molecularmarker assisted breeding or selection may be utilized to reduce thenumber of backcrosses necessary to achieve the backcross conversion. Forexample, see Openshaw, et al., “Marker-assisted Selection in BackcrossBreeding” in: Proceedings Symposium of the Analysis of Molecular Data,August 1994, Crop Science Society of America, Corvallis, Oreg., whichdemonstrated that a backcross locus conversion can be made in as few astwo backcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (a single gene or closely linked genes comparedto unlinked genes), the level of expression of the trait, the type ofinheritance (cytoplasmic or nuclear), dominant or recessive traitexpression, and the types of parents included in the cross. It isunderstood by those of ordinary skill in the art that for single locusor gene traits that are relatively easy to classify, the backcrossmethod is effective and relatively easy to manage. (See Hallauer et al.in Corn and Corn Improvement, Sprague and Dudley, Third Ed. 1998).Desired traits that may be transferred through backcross conversioninclude, but are not limited to, waxy starch, sterility (nuclear andcytoplasmic), fertility restoration, grain color (white), nutritionalenhancements, drought tolerance, nitrogen utilization, altered fattyacid profile, increased digestibility, low phytate, industrialenhancements, disease resistance (bacterial, fungal, or viral), insectresistance, and herbicide tolerance or resistance. A locus conversion,also called a trait conversion, can be a native trait or a transgenictrait. In addition, a recombination site itself, such as an FRT site,Lox site or other site specific integration site, may be inserted bybackcrossing and utilized for direct insertion of one or more genes ofinterest into a specific plant variety. The trait of interest istransferred from the donor parent to the recurrent parent, in this case,an inbred parent of the maize variety disclosed herein.

A single locus may contain several transgenes, such as a transgene fordisease resistance that, in the same expression vector, also contains atransgene for herbicide tolerance or resistance. The gene for herbicidetolerance or resistance may be used as a selectable marker and/or as aphenotypic trait. A single locus conversion of a site specificintegration system allows for the integration of multiple genes at aknown recombination site in the genome. At least one, at least two or atleast three and less than ten, less than nine, less than eight, lessthan seven, less than six, less than five or less than four locusconversions may be introduced into the plant by backcrossing,introgression or transformation to express the desired trait, while theplant, or a plant grown from the seed, plant part or plant cell,otherwise retains the phenotypic characteristics of the deposited seedwhen grown under the same environmental conditions.

The backcross or locus conversion may result from either the transfer ofa dominant allele or a recessive allele. Selection of progeny containingthe trait of interest can be accomplished by direct selection for atrait associated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele, such as the waxy starchcharacteristic, requires growing and selfing the first backcrossgeneration to determine which plants carry the recessive alleles.Recessive traits may require additional progeny testing in successivebackcross generations to determine the presence of the locus ofinterest. The last backcross generation is usually selfed to give purebreeding progeny for the gene(s) being transferred, although a backcrossconversion with a stably introgressed trait may also be maintained byfurther backcrossing to the recurrent parent with selection for theconverted trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype and/or genotype of the recurrent parent. Whileoccasionally additional polynucleotide sequences or genes may betransferred along with the backcross conversion, the backcrossconversion variety “fits into the same hybrid combination as therecurrent parent inbred variety and contributes the effect of theadditional gene added through the backcross.” See Poehlman et al. (1995)Breeding Field Crop, 4th Ed., Iowa State University Press, Ames, Iowa,pp. 132-155 and 321-344.

When one or more traits are introgressed into the variety a differencein quantitative agronomic traits, such as yield or dry down, between thevariety and an introgressed version of the variety in some environmentsmay occur. For example, the introgressed version, may provide a netyield increase in environments where the trait provides a benefit, suchas when a variety with an introgressed trait for insect resistance isgrown in an environment where insect pressure exists, or when a varietywith herbicide tolerance is grown in an environment where the herbicideis used.

The modified X05H214 may be further characterized as having essentiallythe same phenotypic characteristics of maize variety X05H214 such as arelisted in Table 1 when grown under the same or similar environmentalconditions and/or may be characterized by percent identity to X05H214 asdetermined by molecular markers, such as SSR markers or SNP markers.Examples of percent identity determined using markers include at least95%, 96%, 97%, 98%, 99% or 99.5%.

Traits can be used by those of ordinary skill in the art to characterizeprogeny. Traits are commonly evaluated at a significance level, such asa 1%, 5% or 10% significance level, when measured in plants grown in thesame environmental conditions.

Male Sterility and Hybrid Seed Production

Hybrid seed production requires elimination or inactivation of pollenproduced by the female inbred parent. Incomplete removal or inactivationof the pollen provides the potential for self-pollination. A reliablemethod of controlling male fertility in plants offers the opportunityfor improved seed production. There are several ways in which a maizeplant can be manipulated so that it is male sterile. These include useof manual or mechanical emasculation (or detasseling), use of one ormore genetic factors that confer male sterility, including cytoplasmicgenetic and/or nuclear genetic male sterility, use of gametocides andthe like. A male sterile variety designated X05H214 may include one ormore genetic factors, which result in cytoplasmic genetic and/or nucleargenetic male sterility. The male sterility may be either partial orcomplete male sterility.

Hybrid maize seed is often produced by a male sterility systemincorporating manual or mechanical detasseling. Alternate strips of twoinbred varieties of maize are planted in a field, and the pollen-bearingtassels are removed from one of the inbreds (female). Provided thatthere is sufficient isolation from sources of foreign maize pollen, theears of the detasseled inbred will be fertilized only from the otherinbred (male), and the resulting seed is therefore hybrid and will formhybrid plants.

Large scale commercial maize hybrid production, as it is practicedtoday, requires the use of some form of male sterility system whichcontrols or inactivates male fertility. A reliable method of controllingmale fertility in plants also offers the opportunity for improved plantbreeding. This is especially true for development of maize hybrids,which relies upon some sort of male sterility system. There are severalways in which a maize plant can be manipulated so that is male sterile.These include use of manual or mechanical emasculation (or detasseling),cytoplasmic genetic male sterility, nuclear genetic male sterility,gametocides and the like.

The laborious detasseling process can be avoided by using cytoplasmicmale-sterile (CMS) inbreds. Plants of a CMS inbred are male sterile as aresult of genetic factors in the cytoplasm, as opposed to the nucleus,and so nuclear linked genes are not transferred during backcrossing.Thus, this characteristic is inherited exclusively through the femaleparent in maize plants, since only the female provides cytoplasm to thefertilized seed. CMS plants are fertilized with pollen from anotherinbred that is not male-sterile. Pollen from the second inbred may ormay not contribute genes that make the hybrid plants male-fertile, andeither option may be preferred depending on the intended use of thehybrid. The same hybrid seed, a portion produced from detasseled fertilemaize and a portion produced using the CMS system can be blended toinsure that adequate pollen loads are available for fertilization whenthe hybrid plants are grown. CMS systems have been successfully usedsince the 1950's, and the male sterility trait is routinely backcrossedinto inbred varieties. See Wych, Robert D. (1988) “Production of HybridSeed”, Corn and Corn Improvement, Ch. 9, pp. 565-607.

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations asdescribed by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068,describes a system of nuclear male sterility which includes: identifyinga gene which is needed for male fertility; silencing this native genewhich is needed for male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

These, and the other methods of conferring genetic male sterility in theart, each possess their own benefits and drawbacks. Some other methodsuse a variety of approaches such as delivering into the plant a geneencoding a cytotoxic substance associated with a male tissue specificpromoter or an antisense system in which a gene needed for fertility isidentified and an antisense to that gene is inserted in the plant (seeFabinjanski, et al. EPO 89/3010153.8 publication no. 329,308 and PCTapplication PCT/CA90/00037 published as WO 90/08828).

Another system for controlling male sterility makes use of gametocides.Gametocides are not a genetic system, but rather a topical applicationof chemicals. These chemicals affect cells that are needed for malefertility. The application of these chemicals affects fertility in theplants only for the growing season in which the gametocide is applied(see Carlson, Glenn R., and U.S. Pat. No. 4,936,904). Application of thegametocide, timing of the application and genotype specificity oftenlimit the usefulness of the approach and it is not appropriate in allsituations.

Transformation

Transgenes and transformation methods facilitate engineering of thegenome of plants to contain and express heterologous genetic elements,such as foreign genetic elements, or additional copies of endogenouselements, or modified versions of native or endogenous genetic elementsin order to alter at least one trait of a plant in a specific manner.Any sequences, such as DNA, whether from a different species or from thesame species, which have been stably inserted into a genome usingtransformation are referred to herein collectively as “transgenes”and/or “transgenic events”. Transgenes can be moved from one genome toanother using breeding techniques which may include, for example,crossing, backcrossing or double haploid production. In someembodiments, a transformed variant of X05H214 may comprise at least onetransgene but could contain at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10and/or no more than 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2.Transformed versions of the claimed maize variety X05H214 containing andinheriting the transgene thereof are provided.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88 and Armstrong, “The First Decade of Maize Transformation: A Reviewand Future Perspective” (Maydica 44:101-109, 1999). In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick, B. R. and Thompson, J.E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

In general, methods to transform, modify, edit or alter plant endogenousgenomic DNA include altering the plant native DNA sequence or apre-existing transgenic sequence including regulatory elements, codingand non-coding sequences. These methods can be used, for example, totarget nucleic acids to pre-engineered target recognition sequences inthe genome. Such pre-engineered target sequences may be introduced bygenome editing or modification. As an example, a genetically modifiedplant variety is generated using “custom” or engineered endonucleasessuch as meganucleases produced to modify plant genomes (see e.g., WO2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Anothersite-directed engineering method is through the use of zinc fingerdomain recognition coupled with the restriction properties ofrestriction enzyme. See e.g., Urnov, et al., (2010) Nat Rev Genet.11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. Atranscription activator-like (TAL) effector-DNA modifying enzyme (TALEor TALEN) is also used to engineer changes in plant genome. See e.g.,US20110145940, Cermak et al., (2011) Nucleic Acids Res. 39(12) and Bochet al., (2009), Science 326(5959): 1509-12. Site-specific modificationof plant genomes can also be performed using the bacterial type IICRISPR (clustered regularly interspaced short palindromic repeats)/Cas(CRISPR-associated) system. See e.g., Belhaj et al., (2013), PlantMethods 9: 39; The Cas9/guide RNA-based system allows targeted cleavageof genomic DNA guided by a customizable small noncoding RNA in plants(see e.g., WO 2015026883A1, incorporated herein by reference).

Plant transformation methods may involve the construction of anexpression vector. Such a vector comprises a DNA sequence that containsa gene under the control of or operatively linked to a regulatoryelement, for example a promoter. The vector may contain one or moregenes and one or more regulatory elements.

A transgenic event which has been stably engineered into the germ cellline of a particular maize plant using transformation techniques, couldbe moved into the germ cell line of another variety using traditionalbreeding techniques that are well known in the plant breeding arts.These varieties can then be crossed to generate a hybrid maize varietyplant such as maize variety plant X05H214 which comprises a transgenicevent. For example, a backcrossing approach is commonly used to move atransgenic event from a transformed maize plant to another variety, andthe resulting progeny would then comprise the transgenic event(s). Also,if an inbred variety was used for the transformation then the transgenicplants could be crossed to a different inbred in order to produce atransgenic hybrid maize plant.

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences. Forexample, see the traits, genes and transformation methods listed in U.S.Pat. Nos. 6,118,055 and 6,284,953, which are herein incorporated byreference. In addition, transformability of a variety can be increasedby introgressing the trait of high transformability from another varietyknown to have high transformability, such as Hi-II. See U.S. PatentApplication Publication US 2004/0016030 (2004).

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants that areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem. 114: 92-6(1981).

Transgenic events can be mapped by one of ordinary skill in the art andsuch techniques are well known to those of ordinary skill in the art.For exemplary methodologies in this regard, see for example, Glick andThompson, Methods in Plant Molecular Biology and Biotechnology, 269-284(CRC Press, Boca Raton, 1993).

Likewise, by means of the present invention, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of maize the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide tolerance,agronomic traits, grain quality and other traits. Transformation canalso be used to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to maize as well as non-native DNAsequences can be transformed into maize and used to alter levels ofnative or non-native proteins. Various promoters, targeting sequences,enhancing sequences, and other DNA sequences can be inserted into themaize genome for the purpose of altering the expression of proteins.Reduction of the activity of specific genes (also known as genesilencing, or gene suppression) is desirable for several aspects ofgenetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook Ch.118 (Springer-Verlag 1994) or other genetic elements such as a FRT, Loxor other site specific integration site, antisense technology (see,e.g., Sheehy et al.

Nos.5,107,065; 5,453,566; and 5,759,829); co-suppression (e.g., Taylor(1997) Plant Cell 9:1245; Jorgensen (1990) Trends Biotech.8(12):340-344; Flavell (1994) PNAS USA 91:3490-3496; Finnegan et al.(1994) Bio/Technology 12: 883-888; and Neuhuber et al.

(1993) Antisense Res. Dev. 3:253);oligonucleotide mediated targeted modification (e.g., WO 03/076574 andWO 99/25853); Zn-finger targeted molecules (e.g., WO 01/52620; WO03/048345; and WO 00/42219); and other methods or combinations of theabove methods known to those of skill in the art.

(C) A herbicide that inhibits photosynthesis, such as a triazine (psbAand gs+ genes) and a benzonitrile (nitrilase gene). Przibilla et al.,Plant Cell 3: 169 (1991), describe the transformation of Chlamydomonaswith plasmids encoding mutant psbA genes. Nucleotide sequences fornitrilase genes are disclosed in U.S. Pat. No. 4,810,648 to Stalker, andDNA molecules containing these genes are available under ATCC AccessionNos. 53435, 67441 and 67442.

(1995)Mol Gen Genet 246:419). Other genes that confer tolerance to herbicidesinclude: a gene encoding a chimeric protein of rat cytochrome P4507A1and yeast NADPH-cytochrome P450 oxidoreductase (Shiota et al. (1994)Plant Physiol 106:17), genes for glutathione reductase and superoxidedismutase (Aono et al. (1995) Plant Cell Physiol 36:1687, and genes forvarious phosphotransferases (Datta et al.

(E) Protoporphyrinogen oxidase (protox) is necessary for the productionof chlorophyll, which is necessary for all plant survival. The protoxenzyme serves as the target for a variety of herbicidal compounds. Theseherbicides also inhibit growth of all the different species of plantspresent, causing their total destruction. The development of plantscontaining altered protox activity which are tolerant to theseherbicides are described in U.S. Pat.

3. Transgenes that Confer or Contribute to an Altered GrainCharacteristic, Such as:

(A) Altered fatty acids, for example, by

-   -   (1) Down-regulation of stearoyl-ACP desaturase to increase        stearic acid content of the plant. See Knultzon et al., Proc.        Natl. Acad. Sci. USA 89: 2624 (1992) and WO99/64579 (Genes for        Desaturases to Alter Lipid Profiles in Corn),    -   (2) Elevating oleic acid via FAD-2 gene modification and/or        decreasing linolenic acid via FAD-3 gene modification (see U.S.        Pat.

4. Genes that Control Male-Sterility:

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations asdescribed by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068,describe a system of nuclear male sterility which includes: identifyinga gene which is needed for male fertility; silencing this native genewhich is needed for male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

Using X05H214 to Develop Another Maize Plant

The development of maize hybrids in a maize plant breeding programrequires, in general, the development of homozygous inbred lines, thecrossing of these lines, and the evaluation of the crosses. Maize plantbreeding programs combine the genetic backgrounds from two or moreinbred varieties or various other germplasm sources into breedingpopulations from which new inbred varieties are developed by selfing andselection of desired phenotypes. Hybrids also can be used as a source ofplant breeding material or as source populations from which to developor derive new maize varieties. Plant breeding techniques known in theart and used in a maize plant breeding program include, but are notlimited to, recurrent selection, mass selection, bulk selection,backcrossing, making double haploids, pedigree breeding, openpollination breeding, restriction fragment length polymorphism enhancedselection, genetic marker enhanced selection, and transformation. Oftencombinations of these techniques are used. The inbred varieties derivedfrom hybrids can be developed using plant breeding techniques asdescribed above. New inbreds are crossed with other inbred varieties andthe hybrids from these crosses are evaluated to determine which of thosehave commercial potential. The oldest and most traditional method ofanalysis is the observation of phenotypic traits but genotypic analysismay also be used.

Methods for producing a maize plant by crossing a first parent maizeplant with a second parent maize plant wherein either the first orsecond parent maize plant is a maize plant of the variety X05H214 areprovided. The other parent may be any other maize plant, such as anotherinbred variety or a plant that is part of a synthetic or naturalpopulation. Any such methods using the maize variety X05H214 are part ofthis invention: selfing, sibbing, backcrosses, mass selection, pedigreebreeding, bulk selection, hybrid production, crosses to populations, andthe like. These methods are well known in the art and some of the morecommonly used breeding methods are described below and can be found inone of several reference books (e.g., Allard, Principles of PlantBreeding, 1960; Simmonds, Principles of Crop Improvement, 1979; Fehr,“Breeding Methods for Cultivar Development”, Production and Uses, 2^(nd)ed., Wilcox editor, 1987).

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. X05H214 is suitable for use in arecurrent selection program. The method entails individual plants crosspollinating with each other to form progeny. The progeny are grown andthe superior progeny selected by any number of selection methods, whichinclude individual plant, half-sib progeny, full-sib progeny, selfedprogeny and topcrossing. The selected progeny are cross pollinated witheach other to form progeny for another population. This population isplanted and again superior plants are selected to cross pollinate witheach other. Recurrent selection is a cyclical process and therefore canbe repeated as many times as desired. The objective of recurrentselection is to improve the traits of a population. The improvedpopulation can then be used as a source of breeding material to obtaininbred varieties to be used in hybrids or used as parents for asynthetic cultivar. A synthetic cultivar is the resultant progeny formedby the intercrossing of several selected inbreds.

X05H214 is suitable for use in mass selection. Mass selection is auseful technique when used in conjunction with molecular marker enhancedselection. In mass selection seeds from individuals are selected basedon phenotype and/or genotype. These selected seeds are then bulked andused to grow the next generation. Bulk selection requires growing apopulation of plants in a bulk plot, allowing the plants toself-pollinate, harvesting the seed in bulk and then using a sample ofthe seed harvested in bulk to plant the next generation. Instead ofself-pollination, directed pollination could be used as part of thebreeding program.

Production of Double Haploids

The production of double haploids from X05H214 can also be used for thedevelopment of inbreds. Double haploids are produced by the doubling ofa set of chromosomes (1N) from a heterozygous plant to produce acompletely homozygous individual. For example, a method is provided ofobtaining a substantially homozygous X05H214 progeny plant by obtaininga seed from the cross of X05H214 and another maize plant and applyingdouble haploid methods to the F1 seed or F1 plant or to any successivefilial generation. Methods for producing plants by doubling haploid seedgenerated by a cross of the plants, or parts thereof, disclosed hereinwith a different maize plant are provided. The use of double haploidssubstantially decreases the number of generations required to produce aninbred with similar genetics or characteristics to X05H214. For example,see Wan et al., “Efficient Production of Doubled Haploid Plants ThroughColchicine Treatment of Anther-Derived Maize Callus”, Theoretical andApplied Genetics, 77:889-892, 1989 and U.S. Patent Application No.2003/0005479. This can be advantageous because the process omits thegenerations of selfing needed to obtain a homozygous plant from aheterozygous source.

Haploid induction systems have been developed for various plants toproduce haploid tissues, plants and seeds. The haploid induction systemcan produce haploid plants from any genotype by crossing a selectedvariety (as female) with an inducer variety. Such inducer varieties formaize include Stock 6 (Coe, 1959, Am. Nat. 93:381-382; Sharkar and Coe,1966, Genetics 54:453-464) RWS (available online from the UniversitätHohenheim), KEMS (Deimling, Roeber, and Geiger, 1997, Vortr.Pflanzenzuchtg 38:203-224), or KMS and ZMS (Chalyk, Bylich and Chebotar,1994, MNL 68:47; Chalyk and Chebotar, 2000, Plant Breeding 119:363-364),and indeterminate gametophyte (ig) mutation (Kermicle 1969 Science166:1422-1424), the disclosures of which are incorporated herein byreference.

In particular, a process of making seed substantially retaining themolecular marker profile of maize variety X05H214 is provided. Obtaininga seed of hybrid maize variety X05H214 further comprising a locusconversion, wherein representative seed is produced by crossing a firstplant of variety PH1M1K or a locus conversion thereof with a secondplant of variety PH1TRA or a locus conversion thereof, and whereinrepresentative seed of said varieties PH1M1K and PH1TRA have beendeposited and wherein said maize variety X05H214 further comprising alocus conversion has 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% of thesame polymorphisms for molecular markers as the plant or plant part ofmaize variety X05H214. Sequences for the public markers can be found,for example, in the Panzea database which is available online fromPanzea. The type of molecular marker used in the molecular profile canbe but is not limited to Single Nucleotide Polymorphisms, SNPs. Aprocess of making seed retaining essentially the same phenotypic,physiological, morphological or any combination thereof characteristicsof maize variety X05H214 is also contemplated. Obtaining a seed ofhybrid maize variety X05H214 further comprising a locus conversion,wherein representative seed is produced by crossing a first plant ofvariety PH1M1K or a locus conversion thereof with a second plant ofvariety PH1TRA or a locus conversion thereof, and wherein representativeseed of said varieties PH1M1K and PH1TRA have been deposited and whereinsaid maize variety X05H214 further comprising a locus conversion hasessentially the same morphological characteristics as maize varietyX05H214 when grown in the same environmental conditions. The sameenvironmental conditions may be, but is not limited to, a side-by-sidecomparison. The characteristics can be, for example, those listed inTable 1. The comparison can be made using any number of professionallyaccepted experimental designs and statistical analysis.

Use of X05H214 in Tissue Culture

This invention is also directed to the use of maize variety X05H214 intissue culture. As used herein, the term “tissue culture” includes plantprotoplasts, plant cell tissue culture, cultured microspores, plantcalli, plant clumps, and the like. As used herein, phrases such as“growing the seed” or “grown from the seed” include embryo rescue,isolation of cells from seed for use in tissue culture, as well astraditional growing methods.

Duncan, Williams, Zehr, and Widholm, Planta, (1985) 165:322-332 reflectsthat 97% of the plants cultured that produced callus were capable ofplant regeneration. Subsequent experiments with both inbreds and hybridsproduced 91% regenerable callus that produced plants. In a further studyin 1988, Songstad, Duncan and Widholm in Plant Cell Reports (1988),7:262-265 reports several media additions that enhance regenerability ofcallus of two inbred varieties. Other published reports also indicatedthat “nontraditional” tissues are capable of producing somaticembryogenesis and plant regeneration. K. P. Rao, et aL, Maize GeneticsCooperation Newsletter, 60:64-65 (1986), refers to somatic embryogenesisfrom glume callus cultures and B. V. Conger, et aL, Plant Cell Reports,6:345-347 (1987) indicates somatic embryogenesis from the tissuecultures of maize leaf segments. Thus, it is clear from the literaturethat the state of the art is such that these methods of obtaining plantsare, and were, “conventional” in the sense that they are routinely usedand have a very high rate of success.

Tissue culture of maize, including tassel/anther culture, is describedin U.S. Patent Publication 2002/0062506A1 and European Patentpublication EP0160,390, each of which are incorporated herein byreference for this purpose.

Thus, another aspect of this invention is to provide cells whichupon growth and differentiation produce maize plants having the genotypeand/or phenotypic characteristics of maize variety X05H214.

Seed Treatments and Cleaning

Provided are methods of harvesting the grain of the F1 plant of varietyX05H214 and using the grain, F2, as seed for planting. Also provided aremethods of using the seed of variety X05H214, F1, as seed for planting.Embodiments include cleaning the seed, treating the seed, and/orconditioning the seed. Cleaning the seed includes removing foreigndebris such as weed seed, chaff, and non-seed plant matter from theseed. Conditioning the seed can include controlling the temperature andrate of dry down and storing seed in a controlled temperatureenvironment. Seed treatment is the application of a composition to theseed such as a coating or powder. Methods for producing a treated seedinclude the step of applying a composition to the seed or seed surface.Seeds are provided which have on the surface a composition. Someexamples of compositions are insecticides, fungicides, pesticides,antimicrobials, germination inhibitors, germination promoters,cytokinins, and nutrients. Carriers such as polymers can be used toincrease binding to the seed.

To protect and to enhance yield production and trait technologies, seedtreatment options can provide additional crop plan flexibility and costeffective control against insects, weeds and diseases, thereby furtherenhancing the invention described herein. Seed material can be treated,typically surface treated, with a composition comprising combinations ofchemical or biological herbicides, herbicide safeners, insecticides,fungicides, germination inhibitors and enhancers, nutrients, plantgrowth regulators and activators, bactericides, nematicides, avicidesand/or molluscicides. These compounds are typically formulated togetherwith further carriers, surfactants or application-promoting adjuvantscustomarily employed in the art of formulation. The coatings may beapplied by impregnating propagation material with a liquid formulationor by coating with a combined wet or dry formulation. Examples of thevarious types of compounds that may be used as seed treatments areprovided in The Pesticide Manual: A World Compendium, C. D. S. TomlinEd., Published by the British Crop Production Council, which is herebyincorporated by reference.

Some seed treatments that may be used on crop seed include, but are notlimited to, one or more of abscisic acid, acibenzolar-S-methyl,avermectin, amitrol, azaconazole, azospirillum, azadirachtin,azoxystrobin, Bacillus spp. (including one or more of cereus, firmus,megaterium, pumilis, sphaericus, subtilis and/or thuringiensis),Bradyrhizobium spp. (including one or more of betae, canariense,elkanii, iriomotense, japonicum, liaonigense, pachyrhizi and/oryuanmingense), captan, carboxin, chitosan, clothianidin, copper,cyazypyr, difenoconazole, etidiazole, fipronil, fludioxonil,fluoxastrobin, fluquinconazole, flurazole, fluxofenim, harpin protein,imazalil, imidacloprid, ipconazole, isoflavenoids,lipo-chitooligosaccharide, mancozeb, manganese, maneb, mefenoxam,metalaxyl, metconazole, myclobutanil, PCNB, penflufen, penicillium,penthiopyrad, permethrine, picoxystrobin, prothioconazole,pyraclostrobin, rynaxypyr, S-metolachlor, saponin, sedaxane, TCMTB,tebuconazole, thiabendazole, thiamethoxam, thiocarb, thiram,tolclofos-methyl, triadimenol, trichoderma, trifloxystrobin,triticonazole and/or zinc. PCNB seed coat refers to EPA registrationnumber 00293500419, containing quintozen and terrazole. TCMTB refers to2-(thiocyanomethylthio) benzothiazole.

Seed varieties and seeds with specific transgenic traits may be testedto determine which seed treatment options and application rates maycomplement such varieties and transgenic traits in order to enhanceyield. For example, a variety with good yield potential but head smutsusceptibility may benefit from the use of a seed treatment thatprovides protection against head smut, a variety with good yieldpotential but cyst nematode susceptibility may benefit from the use of aseed treatment that provides protection against cyst nematode, and soon. Likewise, a variety encompassing a transgenic trait conferringinsect resistance may benefit from the second mode of action conferredby the seed treatment, a variety encompassing a transgenic traitconferring herbicide resistance may benefit from a seed treatment with asafener that enhances the plants resistance to that herbicide, etc.Further, the good root establishment and early emergence that resultsfrom the proper use of a seed treatment may result in more efficientnitrogen use, a better ability to withstand drought and an overallincrease in yield potential of a variety or varieties containing acertain trait when combined with a seed treatment.

INDUSTRIAL APPLICABILITY

Another embodiment, is a method of harvesting the grain of the F1 plantof variety X05H214 and using the grain in a commodity. Methods ofproducing a commodity plant product are also provided. Examples of maizegrain as a commodity plant product include, but are not limited to,oils, meals, flour, starches, syrups, proteins, cellulose, silage, andsugars. Maize grain is used as human food, livestock feed, and as rawmaterial in industry. The food uses of maize, in addition to humanconsumption of maize kernels, include both products of dry- andwet-milling industries. The principal products of maize dry milling aregrits, meal and flour. The maize wet-milling industry can provide maizestarch, maize syrups, and dextrose for food use. Maize oil is recoveredfrom maize germ, which is a by-product of both dry- and wet-millingindustries. Processing the grain can include one or more of cleaning toremove foreign material and debris from the grain, conditioning, such asaddition of moisture to the grain, steeping the grain, wet milling, drymilling and sifting.

Maize, including both grain and non-grain portions of the plant, is alsoused extensively as livestock feed, primarily for beef cattle, dairycattle, hogs, and poultry.

Industrial uses of maize include production of ethanol, maize starch inthe wet-milling industry and maize flour in the dry-milling industry.The industrial applications of maize starch and flour are based onfunctional properties, such as viscosity, film formation, adhesiveproperties, and ability to suspend particles. The maize starch and flourhave application in the paper and textile industries. Other industrialuses include applications in adhesives, building materials, foundrybinders, laundry starches, explosives, oil-well muds, and other miningapplications.
